The DBH 9830Vit is a radial shaft seal built to keep lubricant in and contamination out of rotating equipment. Its A 316-R AH designation is a DBH configuration code covering lip geometry, material and housing style, so it tells you how the seal is made rather than how big it is. You will find this type of seal in pumps, motors, gearboxes and bearing positions, where a good sealing point is what keeps the assembly running. MR supplies it within its seals and oil seals line for industrial maintenance work.

Because 9830Vit is a configuration code, the three mounting dimensions are not embedded in it. Shaft diameter, housing bore and overall width have to come from the DBH data sheet or from measuring the seal you are replacing. Treat the code as a description of the seal, not as a size, and confirm the assembly before you order.

Seals in this family sit where a rotating shaft passes through a housing and oil or grease has to stay put. Common locations include centrifugal pumps, electric motors, gearboxes, process machinery bearings, mixers and conveyors. In each case the seal holds the lubricant in place and blocks dust, water and particles that would otherwise speed up wear.

Installation matters as much as selection. Inspect the shaft first: no burrs, no scoring, correct surface roughness. Lubricate the lip, then press the seal in by its outer diameter only, never through the lip. When a wear track is already present on the shaft, shifting the seal slightly or fitting a wear sleeve are options worth considering. Speed, temperature and the fluid being sealed drive the final choice.

For an equivalent, send the code 9830Vit along with your shaft and housing dimensions, a photo of the part and the fluid involved. With that information we can identify the DBH option or a comparable seal from another brand. If the original is no longer produced, we can also tell you whether a similar configuration will work in its place.
